Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering technology, specifically to a vehicle seat and a vehicle. Background Technology

[0002] There is usually a gap of about 10mm between the vehicle seat and the surrounding components to ensure that the seat will not interfere with the surrounding components during adjustment. However, because there are soft distal airbags on the side of the seat back, the airbags will shift away from the seat back when squeezed by the passenger. This causes the backrest foam to be pushed away from the seat back, resulting in interference between the seat back and the surrounding components. When the seat back needs to be adjusted, friction noise will be generated between the two, thus affecting the user's riding experience. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "circumferential", "radial", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] As those skilled in the art will understand, existing vehicle seats, especially the driver's and front passenger's seats, have soft distal airbags installed on the sides of the backrest frame to rapidly inflate in the event of a side collision, thus protecting the passenger's life. However, during daily use, when a passenger sits in the seat and leans against the backrest, the airbag is compressed by the passenger and shifts away from the seat, causing the backrest foam to be pushed up in that direction. When the seat back needs to be adjusted, the backrest foam interferes with surrounding components, creating friction noise and reducing the user's riding experience. It also easily causes wear and tear on the seat cover and surrounding components.

[0024] Based on this, please refer to Figure 1 This utility model provides a vehicle seat, including a backrest frame 1, an airbag 2, and a limiting member 3. The airbag 2 is disposed on at least one side of the backrest frame 1 along the width direction of the vehicle. One end of the limiting member 3 is connected to the airbag 2, and the other end is connected to the backrest frame 1 to provide a force to the airbag 2 that approaches the backrest frame 1.

[0025] In this way, the limiting component 3 can continuously provide a force close to the backrest frame 1 to the airbag 2, so that the airbag 2 can remain in its initial position and not shift when subjected to a compressive force away from the backrest frame 1. This ensures that the backrest foam will not be pushed up by the airbag 2, and that there is a gap between the seat back and the surrounding components. When the user adjusts the seat back, there will be no friction noise caused by the interference between the two. This improves the user experience and also avoids friction between the backrest cover 6 and the surrounding components, extending the service life of the backrest cover 6 and the surrounding components.

[0026] It should be noted that the width direction of the vehicle mentioned above is the Y-direction shown in the diagram.

[0027] As an example, the aforementioned limiting member 3 may be a fabric component, with one end connected to the airbag 2 and the other end connected to the backrest frame 1. When the passenger leans against the seat back, the limiting member 3 can provide a force to the airbag 2 toward the backrest frame 1 to prevent the airbag 2 from being squeezed and shifted away from the backrest frame 1.

[0028] In other embodiments, the limiting member 3 may also be made of leather, fiber fabric, etc. Those skilled in the art will understand that the limiting member 3 needs to be directly connected to the surface of the airbag 2; therefore, the material of the limiting member 3 should have a certain degree of toughness and be relatively soft to avoid damaging the surface of the airbag 2.

[0029] For preferred options, please refer to [the following]. Figure 2 and Figure 3The vehicle seat also includes a support member 4; the support member 4 is connected to the backrest frame 1, and at least a portion of the support member 4 is located between the airbag 2 and the limiting member 3. With this arrangement, at least a portion of the support member 4 is positioned between the airbag 2 and the limiting member 3. When a passenger leans against the seat back and exerts pressure on the airbag 2, the support member 4 can share some of the pressure, thereby reducing the force required from the limiting member 3. This ensures a continuous and effective connection between the limiting member 3 and the backrest frame 1, preventing the connection from being damaged by excessive pressure. Simultaneously, the connection between the limiting member 3 and the backrest frame 1 also provides support for the side wings of the car seat back, thereby improving the support and wrapping properties of the side wings of the car seat back.

[0030] In an optional embodiment, the support 4 may be a section of irregularly shaped steel wire. In this embodiment, please refer to... Figure 2 and Figure 3 The support member 4 is provided with a connecting section 40 and a support section 41. The support section 41 is used to contact the airbag 2, and the connecting sections 40 are respectively provided at both ends of the support section 41 and can be connected to the backrest frame 1 by bolts. The support section 41 is an undulating arc-shaped component, which can provide a certain support force while avoiding scratching the surface of the airbag 2 during contact with the airbag 2, thus preventing the airbag 2 from becoming unusable.

[0031] In other embodiments, the support member 4 may be a single metal plate or multiple metal blocks. Those skilled in the art can select a suitable shape of support member 4 based on the size of the airbag 2 and the size of the unused space of the backrest frame 1. This embodiment does not impose any restrictions on this.

[0032] Please refer to Figures 1 to 3 The support member 4 is positioned perpendicular to the vehicle's width direction; the airbag 2 is located on the side of the support member 4 away from the backrest frame 1, and the connection point of the limiting member 3 to the backrest frame 1 is located on the side of the support member 4 closer to the backrest frame 1. Thus, the support member 4 is positioned perpendicular to the vehicle's width direction, and the connection points of the airbag 2 and the limiting member 3 to the backrest frame 1 are located on opposite sides of the support member 4. In addition to sharing some of the force when subjected to significant compressive pressure, the support member 4, in conjunction with the limiting member 3, can also limit the relative position of the airbag 2.

[0033] Specifically, the limiting member 3 provides a force to the airbag 2 towards the backrest frame 1, while the support member 4 located between the airbag 2 and the limiting member 3 prevents the airbag 2 from tilting towards the backrest frame 1 due to the force of the limiting member 3, thus ensuring the relative position of the airbag 2 is fixed. That is, under the combined action of the limiting member 3 and the support member 4, the airbag 2 will not be displaced away from the backrest frame 1 due to the compressive force, thus avoiding interference between the seat back and surrounding components; nor will it tilt towards the backrest frame 1 due to the force provided by the limiting member 3, thus affecting the normal use of the seat back.

[0034] In some embodiments, the support member 4 may also be arranged in a direction at an angle to the vehicle width direction to further define the relative position of the airbag 2, which is not limited in this embodiment.

[0035] Please continue to refer to this. Figures 1 to 3 The vehicle seat also includes a connector 5; the backrest frame 1 has a vertical frame 10, and the vertical frame 10 has a connecting hole (not shown in the figure) along the width direction of the vehicle; the airbag 2 is provided with an outwardly protruding connecting part 20, which passes through the connecting hole and is connected by the connector 5. Thus, by passing the connecting part 20 of the airbag 2 through the connecting hole along the width direction of the vehicle and fixing the airbag 2 to the side of the vertical frame 10 away from the backrest frame 1 using the connector 5, the airbag 2 is installed.

[0036] Specifically, the connecting member 5 can be a bolt, and the connecting part 20 can be provided with external threads. The bolt and the external threads cooperate to fix the airbag 2 and the backrest frame 1. The connecting part 20 can be a regular shape such as cylindrical, prismatic, frustum, or truncated cone, or it can be an irregular shape with an arc surface. The connection between the connecting part 20 and the vertical frame 10 can also be a plug-in connection, snap-fit ​​connection, or welding. Those skilled in the art can reasonably configure the connection method between the airbag 2 and the backrest frame 1 according to the actual situation.

[0037] Optional, please refer to Figure 1 and Figure 3 The end of the limiting member 3 furthest from the airbag 2 is provided with a hook hole 30, which passes through the connecting part 20. In this way, the limiting member 3 is connected to the side of the vertical frame 10 near the backrest frame 1 by hooking. The hooking can ensure the integrity of the limiting member 3 to the greatest extent, especially since the limiting member 3 is a fabric component, which can further improve the connection strength.

[0038] In some embodiments, the limiting member 3 may not be hung on the connecting part 20 of the airbag 2, but may be hung on any protrusion on the side of the vertical frame 10 near the backrest frame 1, or it may be fixed in the mounting hole on the vertical frame 10 by an additional connector (such as a pin or bolt). The connection between the limiting member 3 and the vertical frame 10 may also be glued, and this embodiment does not limit this.

[0039] In a preferred embodiment, one end of the limiting member 3 is sewn onto the airbag 2. This prevents the limiting member 3 from being rigidly connected to the airbag 2, thus not affecting the expansion and contraction of the airbag 2 and ensuring its usability. In other embodiments, one end of the limiting member 3 may also be adhered to the outer surface of the airbag 2.

[0040] Please continue to refer to this. Figure 1 and Figure 3 The sewing position of the limiting member 3 and the setting position of the connecting part 20 are respectively located at both ends of the airbag 2 along the width direction. By setting the sewing position of the limiting member 3 and the setting position of the connecting part 20 at both ends of the width direction of the airbag 2, the other end of the limiting member 3 needs to be partially covered by the outside of the support member 4 during the hanging process of the connecting part 20, which further limits the relative position of the airbag 2. This ensures that the airbag 2 will not move on the side of the backrest fastener when subjected to compression or force, thus affecting the passenger's riding experience.

[0041] It should be noted that the width direction of the airbag 2 mentioned above is the X direction in the figure.

[0042] Please refer to Figure 4 The vehicle seat also includes a backrest foam (not shown in the figure) and a backrest cover 6; the backrest foam covers the outside of the backrest frame 1, the airbag 2 and the limiting member 3; the backrest cover 6 is fitted on the outside of the backrest foam.

[0043] In this configuration, the backrest foam covers the outside of the backrest frame 1, airbag 2, and limiting member 3. This design supports the passenger's spine and muscles, absorbs pressure from the body on the backrest, provides a soft touch, and reduces discomfort from a hard surface. Furthermore, it absorbs impact energy and reduces acceleration during a collision. The backrest cover 6, fitted over the backrest foam, protects the foam and its internal frame structure from wear, tear, scratches, and dirt, extending their lifespan. It also enhances the feel of the vehicle seat and improves the passenger experience.

[0044] In this embodiment, the airbag 2 is installed inside the backrest foam and the backrest cover 6. When the vehicle is involved in a side collision, the airbag 2 can quickly inflate and lift the backrest foam and the backrest cover 6 to protect the safety of the passengers.

[0045] In another embodiment, the present invention also provides a vehicle including the vehicle seat described above. Thus, by using the aforementioned vehicle seat, one end of the limiting member 3 is connected to the airbag 2, and the other end is connected to the backrest frame 1, continuously providing a force close to the backrest frame 1 to the airbag 2. This prevents the airbag 2 from shifting away from the backrest frame 1, maintaining the flatness of the backrest foam, ensuring a constant gap between the seat back and surrounding components, preventing interference, and eliminating frictional noises during passenger adjustments, thereby improving the user's riding experience.

[0046] As an optional embodiment, the vehicle also includes a center armrest (not shown in the figure); the center armrest is located on one side of the vehicle seat along the width of the vehicle; the airbag 2 is located on the side of the vehicle seat near the center armrest, and the limiting member 3 is used to provide a force to the airbag 2 near the backrest frame 1, so as to move the airbag 2 away from the center armrest. With this configuration, the limiting member 3 on the side of the driver and passenger seats near the center armrest can effectively prevent the airbag 2 from shifting towards the center armrest due to passenger leaning, and from causing friction noise by pushing up the backrest foam.

[0047] Of course, in other embodiments, a limiting member 3 may also be provided on the side of the vehicle seat away from the center armrest to prevent the airbag 2 from shifting away from the vehicle seat under force and to lift up the backrest foam, causing interference with the door and / or the side wall of the cockpit.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications or equivalent substitutions made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
